Web8 de jun. de 2024 · The technology had its start 60 years ago in Midland, Michigan, with the pairing of two powerful analytical techniques — gas chromatography (GC) and mass spectrometry (MS). By coupling the ability of GC to separate a chemical mixture with the ability of MS to identify its components, the new, combined technique proved revolutionary.

Web“The basic principle of mass spectrometry (MS) is to generate ions from either inorganic or organic compounds by any suitable method, to separate these ions by their mass-to-charge ratio ( m/z) and to detect them qualitatively and quantitatively by their respective m/z and abundance. WebMass spectrometers have three main components: the ion source, the mass analyzer, and the detector, sometimes referred to as the electrometer. In MS, analytes are transferred into the gas phase, charged, filtered, and detected based on the mass-to-charge ( m/z) ratio.
WebGas chromatography combined with a triple quadrupole mass spectrometry system is referred to as GC-MS/MS. The triple quadrupole MS provides a higher level of selectivity and is best suited to analyses where the highest sensitivity is required. This is often the case when quantitating pesticides in food or environmental contaminants. WebThis article will first explain the principles of mass spectrometry in terms of the most basic required instrumentation and the way a measurement is made, followed by an explanation of the mass spectrum, which is the data resulting from an MS measurement. Mass spectra contain a great deal of information that can be complicated to interpret.
WebThe electrons emitted from the electron emitter collide with the molecules of the makeup gas, resulting in many more free electrons. The electrons are accelerated towards a positively charged anode, generating a current. There is therefore always a background signal present in the chromatogram.
